I seem to be experiencing the same bug in debian unstable (amd64) after upgrading to:
akonadi-backend-sqlite 1.6.2-2+b1 akonadi-backend-mysql 1.6.2-2 mysql-common 5.5.23-2 mysql-server-core 5.1.62-1 libmysqlclient18 5.5.23-2 I also have libmysqlclient16 5.1.62-1 installed. Even after running 'akonadictl stop && rm -r ~/.local/share/akonadi' I am unable to start either kmail or akonadiconsole; see attached log files. Hopefully the bug Erik found in mysql will solve this frustrating problem with akonadi and kmail!
